The focus is always on Spongebob or one of his friends, but his chill pet snail Gary always has a few lines in every episode – even if it’s just a meow. He might not act at all like an undersea snail, but he does hiss, bathes, and reacts just like an above-water cat.
Despite the fact that Spongebob has been on the air since 1999, Gary is one of the newer members of this list, but his helpful attitude makes him a welcome addition to this list. He’s been around for longer than the average sea snail, and he’s still going strong.
Kagechiyo from “Ninja Hattori”
Kagechiyo is a black and white cat that has the Koga symbol on his forehead, with large teeth and a shrill voice. He's a fierce, gung-ho warrior that never backs down, and often works as Kamumaki's messenger and fights alongside him. Kagechiyo is, however, not as evil as his boss, and will sometimes help Hattori with his missions.
He wears his treasured red scarf for luck and likes to sing when in a good mood. Like most cats, he enjoys fish. Seeing as he is a cat and his owner also has a dog, it's natural that the two animal characters frequently end up fighting.
Hobbes from “Calvin and Hobbes”
Pet? Toy? Somewhere in between? We aren't going to decide, but we figure he's close enough one way or another. As the rowdy Calvin's constant companion, Hobbes the stuffed tiger helped him build snowmen, avoid homework, play Calvinball, and read comics – when he wasn't terrorizing the child as a hunting tiger does.
The two discussed deep philosophical topics, adventured through the woods, and made us all a little better during the time the comic strip ran. The question remains: was Hobbes really turning into a tiger? Or was it all in Calvin's head? One way or another, we all loved the pair.
Zero from “The Nightmare Before Christmas”
Despite being a ghost dog, Zero acts very much like any regular dog. He loves fetching bones (that are part of Jack Skellington's body). He's also quite perceptive, showing reservation when Jack develops an unhealthy obsession with Christmas – vindicated when the obsession turns out to be a disaster.
His primary concern is Jack's happiness, and so even though he didn't like the obsession, Zero helped out Jack, trying to guide him in the right direction. With a glowing jack-o-lantern nose at the end of his long snout, he ends up taking the Rudolph spot as Jack masquerades as Santa Claus.
Nermal from “Garfield”
Making his first appearance in 1979, Nermal immediately started to get on Garfield's nerves. He was often mistaken for a female due to his long eyelashes and the feminine tone of his voice. However, this is because Jim Davis tends to give young characters long eyelashes.
Nermal often intentionally annoys Garfield and Odie, prompting Garfield to try and mail him to Abu Dhabi. Much to Garfield's dismay, Nermal often shows up on Garfield's birthday. He proclaims himself the cutest kitten in the world, and despite annoying Garfield, sees the bigger cat as his best friend. With a mixture of devious brilliance and cuteness, Nermal is a one-of-a-kind kitty.
